Description The **SoVRMLInterpolator** class is an internal abstract class. This class collects the two fields that are common for all interpolator nodes, plus common code that operates on these fields. Since this is an abstract "helper" class, it does not represent an actual node from the VRML97 specification, so don't use it as such. For more information, a detailed discussion of interpolators is available in section 4.6.8 of the VRML97 specification: http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.8 ## Member Function Documentation ### SoType SoVRMLInterpolator::getClassTypeId (void ) \[static\] This static method returns the **SoType** object associated with objects of this class. ### SoType SoVRMLInterpolator::getTypeId (void ) const \[virtual\] Returns the type identification of an object derived from a class inheriting **SoBase**. This is used for runtime type checking and "downward" casting. Implements **SoBase**. Reimplemented in **SoVRMLColorInterpolator**, **SoVRMLCoordinateInterpolator**, **SoVRMLNormalInterpolator**, **SoVRMLOrientationInterpolator**, **SoVRMLPositionInterpolator**, and **SoVRMLScalarInterpolator**. ### const SoFieldData \*\* SoVRMLInterpolator::getFieldDataPtr (void ) \[static\], \[protected\] *This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\ Returns the **SoFieldData** class which holds information about fields in this node. ### const SoFieldData \* SoVRMLInterpolator::getFieldData (void ) const \[protected\], \[virtual\] Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. Reimplemented from **SoFieldContainer**. Reimplemented in **SoVRMLColorInterpolator**, **SoVRMLCoordinateInterpolator**, **SoVRMLNormalInterpolator**, **SoVRMLOrientationInterpolator**, **SoVRMLPositionInterpolator**, and **SoVRMLScalarInterpolator**. ### const SoEngineOutputData \* SoVRMLInterpolator::getOutputData (void ) const \[virtual\] *This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\ Implements **SoNodeEngine**. Reimplemented in **SoVRMLColorInterpolator**, **SoVRMLCoordinateInterpolator**, **SoVRMLNormalInterpolator**, **SoVRMLOrientationInterpolator**, **SoVRMLPositionInterpolator**, and **SoVRMLScalarInterpolator**. ### void SoVRMLInterpolator::initClass (void ) \[static\] ### int SoVRMLInterpolator::getKeyValueIndex (float & interp, int numvalues) \[protected\] *This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\ ## Member Data Documentation ### SoMFFloat SoVRMLInterpolator::key This field contains a set of floating point values which the interpolation will run over. The key values should be monotonically non-decreasing. The field is inherited from its declaration in the abstract **SoVRMLInterpolator** class into a range of different VRML interpolator nodes. See the class documentation of the *non-abstract* VRML interpolator node you want to use for information on what the key values represent in that specific context. ### SoSFFloat SoVRMLInterpolator::set\_fraction The set\_fraction field gets an input signal that triggers a calculation of the next value\_changed eventOut value. The field is inherited from its declaration in the abstract **SoVRMLInterpolator** class into a range of different VRML interpolator nodes. ## Author Generated automatically by Doxygen for Coin from the source code.
